Title: Copper wiring manufacture, semiconductor device, and copper wiring manufacture device
Inventor: TAKAHASHI SEIICHI
IPC: C23C16/34
Filed: 1995-02-10
Abstract: PURPOSE: To form copper wiring by simple process without using a wet process. CONSTITUTION: A barrier layer 5 and a high polymer film 6 are made in this order on an insulating film 3 grown on a substrate 2, and a groove 4 provided in the insulating film 3 is charged with a high polymer film 6, and the high polymer film is etched back, and the barrier layer is etched, protecting the barrier layer within the groove 4 with the high polymer film, and next the high polymer film is ashed, whereupon a wafer where base barrier layer 7 consisting of the barrier layer 5 is made in the groove can be obtained. Performing selective growth of copper for this wafer will grow a copper film only on the surface of the base barrier layer, and charge the groove with a copper film, so copper wiring can be made without performing wet processing.

Title: Method for forming capacitor of semiconductor device
Inventor: TAKAHASHI MASASHI
IPC: H01L27/04
Filed: 1993-03-08
Abstract: PURPOSE:To relax concentration of electric field at the recessed and projecting parts on the surface of a storage electrode by setting the film thickness of a first silicon oxide film out of a capacitor insulation film consisting of the first silicon oxide film, silicon nitride film, and a second silicon oxide film. CONSTITUTION:After a storage electrode 28 is formed, oxidation is made to form a first silicon oxide film 29a. The film thickness of the silicon oxide film 29a is controlled to be within 2.5nm-4.0nm. Then, after silicon oxide film 29b is deposited, one part of the upper part of the silicon nitride film 29b is oxidized to form a second silicon oxide film 29c which is approximately 2nm. When the film thickness of the silicon oxide film 29a is thinner than 2.5nm, the life is short and the effect is small. When it becomes thick, the influence of the ground becomes larger so that the thickness should be smaller than 4.0nm, thus relaxing the concentration of electric field at the recessed and projecting part on the surface of the storage electrode and improving the characteristics of the capacitor insulation film such as TDDB characteristics.

Title: System for extracting unregistered word
Inventor: NAGASE YUKI
IPC: G06F17/28
Filed: 1988-02-29
Abstract: PURPOSE:To highly exactly extract the unregistered word of a long HIRAGANA (Japanese syllabary) by segmenting a partial character string from an inputted sentence with centering a character position deadlocked to a morpheme analysis, paying an attention to a postpositional word from this partial character string and extracting the HIRAGANA unregistered word. CONSTITUTION:A character string segmentation part 2 morpheme-analyzes the inputted sentence with a morpheme analysis part 1 and the partial character string, in which an unregistered word vocabulary is supposed to exist with centering the character position deadlocked to the morpheme analysis, is segmented from the inputted sentence. An unregistered word extraction part 3 pays an attention to the postpositional word in this segmented partial character string and extracts the unregistered word of a significant HIRAGANA. Thus, since the partial character string is segmented from the inputted sentence with centering the character position unable to morpheme-analyze and the extraction of the unregistered word of the significant HIRAGANA is executed, when the registered word of the long HIRAGANA can be highly exactly extracted.

Therefore, the picture is not longitudinally longer on the monitor TV of the aspect ratio a2 and is normally projected. The switchgear 415 is so operated that the reproduced signal is outputted to the monitor TV of the aspect ratio a2 as it is and is outputted to the monitor TV of the aspect a1 after having the time base expanded a2/a1 times when the aspect ratio of the reproduced signal is a2. Therefore, the picture is not transversely longer on the monitor TV of the aspect ratio a1 and is normally projected.
